What Clients Say…
Marni is an exceptional coach—deeply committed to her clients and craft—whose work delivers unmistakable, game-changing leadership results.
I had a tremendous experience working with Marni for over three years under two separate engagements. Marni’s work accompanied my expansion as a leader from a local geographic lead to a broad executive regional role where my leadership required immense growth in ways I could not have imagined. Marni’s forward thinking and deep interpersonal approach helped catapult my abilities and ground my leadership skills into an authentic experience where I combined skills learned with heartfelt and personal passion.
There are two core elements that define Marni’s extraordinary effectiveness as an executive coach. First, she creates a vital space away from the daily grind—one that’s both strategic and reflective—where her sharp intuition and holistic perspective allow her to offer consistently meaningful guidance and leadership tools. Her insights are not only practical but deeply resonant.
Second, Marni brings a profound human connection to her work. She cultivates a level of trust and authenticity that makes the inward journey both powerful and transformative. Her ability to connect on this level enables deep, lasting growth.
I would highly recommend any leader who is committed to authentic and interpersonal leadership to consider Marni as part of their trusted circle of advisors.

Marni helped me re-gain a belief in myself – and win a very competitive promotion.
Marni is an exceptional executive coach. At a pivotal moment in my career, she helped me rebuild confidence following significant organizational change. Her pragmatic techniques improved my conscience presence and were instrumental in my advancement.
Our work together also gave me the clarity, courage, and momentum to move forward with conviction. I’m now fully engaged, performing at a higher level, and making a meaningful impact.
Joe Linnehan, Director, Slalom
I would not be where I am today without my partnership with Marni.
I started working with Marni three years ago as my executive coach. I wasn’t paired with her, but rather I selected her after interviewing several coaches due to her energy and communication style. I had no way of knowing then what an impact her coaching would have on me and those around me.
I sought out an executive coach to help me refine my greatest strengths to increase my executive presence and impact, while wanting to learn how to tame the less desirable behaviors that were getting me in the way of my professional goals. While I had received consistent feedback over the years, I never knew what to do with it.
I can confidently say that working with Marni has helped me build the tool kit to be the best professional version of myself. And those same skills have been applicable in my personal life.

Marni enabled me to find clarity, regain my purpose — and course-correct into my desired fulfillment.
There are pivotal times professionally when you realize that you’re not on the right path to fulfillment. You think you are—and outside influences lead you to believe you are—but you’re not! Through discussions with Marni and her suggested readings and tips, I had a massive epiphany. The “thing” professionally I was manically driving towards, and thought was my end desired state, wasn’t my end game at all.
Marni enabled me to find clarity and regain my purpose & desired fulfillment. Once that clarity took hold, the new path forward revealed itself. I couldn’t be more grateful … and happy! If you’re like me and desire to consistently reevaluate, refine, and elevate you’re thinking and tool set, there’s no better executive coach to have by your side than Marni.

Marni has been a force of growth, accountability, encouragement, and inspiration to me for over a year now. Her approach is holistic and integrated: she ties together so many developmental principles into one coaching experience. In that period of rapid advancement involving brand-new territory, she coached me to excel: to provide servant leadership to my team amidst tremendous change while balancing all the facets of running a successful business. Marni challenges me, coaches me through crucial decisions and provides an avenue for processing some of the biggest professional hurdles I’ve ever encountered. She has been invaluable to me as a leader.

Marni will get you out of your comfort zone and accelerate your growth as a leader and executive.
After a few sessions, she will know you better than you know yourself! I was always impressed how well she understood business and team situations that I shared … like she was right there with me even though we worked together remotely.
Marni will understand your unique qualities that make you an authentic leader– and ask you to develop new skills that you did not realize you needed: she taught me to be a direct communicator and to have Crucial Conversations with colleagues.
I’m grateful for my coaching sessions with Marni and especially thankful that she taught me the importance of a consistent meditation practice. As a result of the time I spent with Marni, I approach situations in all parts of my life with more clarity, wisdom, and effectiveness. I can highly recommend her coaching services!

Marni Gauthier has the range and agility to meet her clients where they are – and to walk with them to their desired destination.
Rather than applying any single methodology, she listens hard, then draws from a wide variety of theories and approaches to provide insight and tools which help her clients to change their state. I found this tremendously useful, as it enabled me to focus on communicating my situation, trusting that Marni would make the effort to understand, and to suggest genuinely relevant and useful new behaviors. This worked really well, and months later I’m still finding ways to improve based on Marni’s input.

Marni knocked it out of the park!
You can’t teach what she does. She listens to everybody in the room and brings back the various points to weave them into relational learning.

This program proved to be a small investment with large, sustained returns—in both leadership and business results.
With the world climate and pressures of today, being afforded this opportunity to look at myself and evaluate how I am perceived by others was an absolute eye opener. By highlighting positive leadership qualities and areas of focus to improve, I was able to humbly put into action small changes in my daily routines that provided great results. Marni’s technique of helping to self-identify opportunities within my management style and truly understanding how they impact others proved to be a springboard in both my personal and professional lives.

Working with Marni accelerated the refinement of my leadership style to meet the needs of a challenging role.
Marni stood out immediately as different from other coaches. She is practical and pragmatic, but also deeply intuitive and vision focused. She asked hard questions, listened with empathy, and pinpointed both my strengths to leverage and my growth areas in a way prior managers and mentors hadn’t distilled so clearly. Marni exposed the path forward for meaningful change.
Over the course of our engagement, we were able to focus on applying structured frameworks to the messy problem of the moment for immediate benefit. Her workshopping approach balanced actions and mindset so that I could adopt new practices and stay authentic. With Marni, I was able to candidly reflect and iterate.
The value of Marni’s coaching is ongoing. The work we did together is now part of my permanent toolkit, providing a resource for both setting my vision for change and the ways to accomplish it.

Marni helped me navigate key leadership challenges in a new, complex role–I’m more successful because of her!
Marni is an exceptional executive coach. She and I worked together during a 15-month period in which I was taking on a new, more challenging, and more complex role than I had ever had before. Marni helped me navigate the key challenges in that role with tremendous curiosity, empathy, and expertise. She brought effective tools to bear and helped me tailor them for my specific context. I can say without a doubt that I’m more successful in my role because of her!
Amit Koren, CEO Leasing and Capital Markets Technology, JLL
Marni truly helped me become ‘unstuck’ and get back onto a growth path — empowering my approach to new challenges in an expanding role within a complex organisation.
She was incredibly empowering in helping me to identify and address areas for potential development. She is incredibly responsive, tailoring her approach to the time and context of each different facet we worked on, always asking ‘what is it time for now.’ She was also very intuitive at spotting patterns, regularly applying appropriate frameworks to recurring challenges across different contexts, sometimes in situations where my own closeness to the topics made it hard to see common threads. Over the course of our engagement, Marni truly helped me to become ‘unstuck’ and get back onto a growth path. We also spent a lot of time laughing! I wouldn’t hesitate to recommend Marni to anybody seeking a reboot in approach to their professional growth.
Product Design leader, JLL
Marni has been an invaluable sounding board and advisor at a critical point in my career.
She has been a delightful coach and partner to work with over the course of our nine-months journey together. I especially appreciate the structure she brings while flexing to meet me where I am in the moment. We’ve talked through numerous concepts and practiced a variety of tools. While our conversations remain fluid, it has been eye-opening to look back and realize how much these concepts thread through the scenarios we’ve discussed in each meeting. Marni also has a gift of helping me gain clarity and shifting my perspective to one that is more productive and empowering. She does all this while modeling the utmost compassion and firmness.
Zhi Xu Martinez, Senior Leader, Vanguard
Marni tackled difficult conversations and built a critical communication bridge between leadership and the working force that enabled our desired cultural shift.
Following a lot of change in a short period of time, our core issues came down to Trust and Communication. Marni’s cultural intervention included Crucial Conversations, Trust and Emotional Intelligence programs for the Executive and Management Teams. She tackled difficult conversations and kept us focused on our desired cultural shift. She created a critical communication bridge between departments and management — between leadership and the working force in touch with the pulse of what was truly happening at the staff level.
Meghan Wong, MS, Director, Medical Management Group Association
Best program experience in my entire career because of Marni’s ability to integrate the mind, body, and emotional elements of executive presence.
Her holistic, ‘whole person’ approach to facilitation and coaching resonated with me greatly. She was a great listener–fully engaged and present with me and the group.
